Notes

  • Make Ahead & Freezing Instructions: This snack mix can be prepped a week ahead of time and refrigerated until ready to serve. You can also prepare and freeze this snack mix for up to 3 months. Thaw in the refrigerator or at room temperature before serving.
  • White Chocolate: Opt for 4-ounce white chocolate baking bars from reputable brands like Bakers or Ghirardelli in the baking section near the chocolate chips. You'll require 4 bars to get 15 ounces. Alternatively, almond bark or white/vanilla melting chips are excellent choices, typically available in the seasonal aisle of your grocery store.
    Tips for melting white chocolate: 
    1. Chop the Chocolate: If you're using a bar of white chocolate, chop it into small, uniform pieces. This helps it melt evenly and more quickly.
    2. Dry Utensils and Bowls: Ensure that all utensils and bowls are completely dry. Even a small amount of water can cause the chocolate to seize and become grainy.
    3. Low and Slow Heat: White chocolate burns easily, so melt it over low heat. If using a microwave, use a low power setting and heat in short bursts, stirring between each burst.
    4. Use a Double Boiler: A double boiler allows for gentle, indirect heat. Fill the bottom pot with an inch or two of water and heat until it's simmering, not boiling. Place the chopped chocolate in the top pot or glass bowl and stir gently as it melts.
    5. Microwave Method: Microwave for 20 seconds at 100 percent power or 30 seconds at 50 percent power, then stir. Repeat until the chocolate is mostly melted, then stir to completely melt the last remaining bits of chocolate.
